Sui generis

Sui generis (pronounced [ˈs(j)uːaɪ ˈdʒɛnərɪs] or [ˈsuːɪ ˈdʒɛnərɪs]) is a term from Latin. It can be translated to Of (his/her/its) own kind. It basically means that something has very special characteristics. They are so special, that the thing cannot really be compared to anything else. It is used in various contexts. The term was invented by philosophers. What they originally wanted to say was that an idea is so specific as to be unique, that it cannot really be part of a broader concept.

In the sociology of Emile Durkheim, sui generis is used to illustrate his theories on social existence. He says that society, as it was there before any living individual was born, is independent of all individuals. His sui generis (its closest English meaning in this sense being 'independent') society will furthermore continue its existence after the individual ceases to interact with it.

Martin Kettle in The Guardian said about hung parliaments: "Each is sui generis, dependent on the particular parliamentary arithmetic, inter-party momentum and surrounding political circumstances."[2]

Slate has used the term several times; one article discussed the unique variations of French Rose Champagne: "Grower Champagnes are wines made by small farmers in the Champagne region who, bucking convention, choose to craft their own wines rather than sell their grapes to the major Champagne houses. Typical of farmer fizzes, the grower rosés are utterly sui generis—in a few cases almost freakishly so."[3]

A CNNThe Marquee post said about James Brown, "I can't even begin to talk about his importance. He was sui generis."[4]

Political commentator Dick Morris referred to the intense public interest in the 2008 US Presidential race as "clearly sui generis, and anything can happen."[5]
